Elastomer waterproofing membrane

Elastomer waterproofing membranes are different from some waterproofing membranes such as SBS modified bitumen waterproofing membranes, which need to be fired before they can be pasted. Self-adhesive waterproofing membrane is convenient for construction (no open flame is required), and when used with certain base treatment agents, it is easier to stick to the surface of the structure, and it is not easy to produce hollow drums. Self-adhesive waterproofing membrane does not use adhesives and hot asphalt during construction, so there is zero smoke emission during the entire construction process, and there is no need to use large-scale equipment, and there is no noise pollution during the construction process. , So we believe that environmental protection is a major advantage of self-adhesive waterproofing membranes.





Lay self-adhesive waterproof membrane. 　Unfold the roll material and align it with the reference line for trial laying, and pay attention to the paper isolation film facing down (when not paper isolation film, the PE isolation film facing down). 　Flat roll material paving: roll up the roll material from one end, and cut the paper release film out of the roll at the length of the roll with a paper knife, being careful not to cut through the roll material. After placing the 12 rolls in place, pull the torn release paper (film) head evenly and forcefully pull it back, while pulling and laying, pay attention to exhaust when laying, the coils are required to be laid tightly and firmly adhered to the base layer .

The distance between the exhaust ducts of the elastomer waterproofing membrane should be 6 meters vertically and horizontally, and should not be blocked, and connected to the exhaust holes connected to the atmosphere. Before the construction of the drainage roof waterproof layer, check whether the exhaust ducts are blocked and clean them. dredge. It is not very difficult to make a waterproof layer of roofing coiled material. As long as we follow the roofing coiled material waterproofing process, implement layer by layer, strictly check, and carefully do every step of the work according to the specifications, we can prevent roof leakage caused by construction. .

The moisture content is not more than 9%, it is flat and compact, and the ends of each node are neatly and complete, and meet the requirements. 　 Road waterproof layer. 　, to lay a flexible waterproof layer, you can choose paint or coiled material. The construction conditions require that the moisture content of the base surface is not greater than 9%, so it is suitable for construction in summer when the weather is hot and sunny for 5 consecutive days. After completion, a water storage experiment should be done. For waterproofing, take one cloth and two coats as an example: After cleaning the base layer, brush the paint completely, and after drying to form a film, lay a layer of glass fiber cloth carcass reinforcement, and brush it all over the flattened surface One layer of paint is fixed, and the next paint application is carried out after drying. base surface requirements. 　The base surface is cleaned up.


The root of the parapet is leaking. Phenomenon. 　The waterproof layer is hollowed along the inner corners of the roots of the parapet, cracks, cracks in the parapet masonry, cracks in the top, the gable is pushed out of the wall, and rainwater pours into the inner wall from the gap. Cause Analysis. The leveling layer, rigid waterproof layer, etc. are directly close to the parapet wall during construction, and no splitting joints are left. The long parapet masonry does not have expansion joints. Under the action of temperature difference, the gable and parapet walls are cracked, and the roots of the parapet wall are not Make an arc according to the regulations, and the waterproof layer of the rolled material is not used as a buffer layer according to the regulations. The end of the rolled material is not sealed well, causing cracks, opening and water leakage.

But what I want to say is that waterproof membranes are not suitable for home improvement, so where are waterproof membranes mainly suitable? 　Waterproof coiled material is a roll of waterproof material made of thick paper or fiber fabric as the base and impregnated with asphalt or other synthetic polymer waterproof materials. It is mainly used for building walls, roofs, tunnels, highways, landfills, etc. It is a flexible building material product that can be rolled into a roll to resist external rainwater and groundwater leakage.





Some complicated parts should be handled well, the detailed nodes should be sealed, and then glued and connected with the additional layer. Especially at the corners, additional layers should be pasted. 　Construction and construction of the waterproof layer, evenly spread the adhesive on the base layer, and then immediately spread the coiled material to paste. When pasting, the air under the coil should be drained, and the excess adhesive should be cleaned afterwards. 　The construction process of the polyethylene polypropylene composite waterproof membrane is not very complicated, but there are many precautions that require us to pay more attention, so that the polyethylene polypropylene composite waterproof membrane can be better used and its great performance can be exerted. Polyethylene polypropylene fiber composite waterproof membrane. 　Before construction.


The closing treatment of the parapet wall: When making cement mortar, it is necessary to wipe the internal corners of the wall and the roof into small rounded corners with a radius of about 50mm. After the base surface meets the requirements, first apply a polyurethane waterproof layer, and apply it immediately after it is evenly applied. A layer of carcass reinforcement layer (glass fiber cloth), and then a second polyurethane waterproof layer, which is firmly bonded to the base surface, and is also convenient for the construction of self-adhesive coils. 　The treatment of the yin and yang corners and the mouth of the pipe: the yin and yang corners must be made with mortar to make 50mm rounded corners, and an additional waterproof layer shall be added, and a glass fiber cloth shall be provided in the additional layer. Look at the logo. According to product standards, the outer packaging of the product should be marked with the company name, product mark, production date or batch number, production license number, storage and transportation precautions, and product marking should be strictly in accordance with the standard, consistent with the product name, and must not be ambiguous Incomplete words or marks and no production marks. When choosing these products, users must pay attention to the product label and recognize the product name, because the label represents the identity of the product. 　By the feel.
